The Model 60 Rotary Reamer utilizes a simple non-sealed bearing design making it cost-effective to run in many applications. It is available in a broad range of hole sizes from 4 1/8 inches to 33? inches and offers a choice of two cutter designs. The Model 62 offers a large bore feature available only on tools from 6 1/2 inch to 8 3/4 inch hole size. Both models come in three- and six-point reamers for bottom hole and string placement. Cutters are retained using a simple design that is easily serviced by rig personnel using common hand tools.

• Large diameter, carburized and hardened pins serve as robust abrasion-resistant bearing sections.
• True rolling reamer cutters offer two cutting structure options. The &ldquoType Q&rdquo cutter achieves maximum reaming action in medium to hard formations where crushing action against the formation is preferred. Hardfaced, carburized steel teeth ground to gauge provide a wear-resistant reaming structure. &ldquoKnobby&rdquo cutters use tungsten carbide inserts to fracture the rock, and are recommended for use in hard formations.

• Standard runs using milled tooth rock bits, drilling surface hole and shallow wells
• High temperature conditions
• High rotary speed applications for the Model 60 due to its large bearing area and open circulation

• When ordering extra blocks, please specify hole size followed by the model number Example: 12 1/4" hole size, Model 60
• 33 7/8" tool available in four-cutter configuration only

• Three-point or six-point
• Bottomhole or string reamer
• Hole size
• Drill collar OD
• Type of cutters to be installed in the reamer
